NASA about to announce Existence of Aliens

Just wait till they get hold of Voyager

Not sure how that would work.

Laser light is essentially light waves marching in step like a body of soldiers (as opposed to normal light which is like a crowd of pedestrians wandering and strolling around out of any sync).

Radio is just a longer wavelength of light than visible light, and actually masers predated lasers (masers are microwave radiation with waves synchronized in the same way that they would later applied to visible light to create lasers, and ultraviolet light to make "Blu Rays".

It would take a super powerful transmitter, and it might also take a maser, or laser, type use of radio to keep the radio waves in sync. The aliens might beam a broadcast right at our star with laser-zed radio, or TV transmission. And it might stay undistorted enough for a long enough distance for us to decipher it . Or (if thei intent is to communicate)they could just send us something like morse code. Like just send beeps. And have the beeps come in sequences of say, the Fibronacci sequence of numbers to show intelligent intent.

being that nobody as yet has done that, it could be that the distances are too great, and the lifespan of intelligent techy civilizations is too short, for us to ever meet with present-day tech. I wonder If we have sent out morse code or Fibonacci or such to other places? seems our v-ger is the major thing we have sent out with the intent of communicating our humanity to anybody else in a way that gets past the power limits of our present tech.

Folks have proposed communications of that sort even prior to radio mass communication.

A French astronomer in the 18th or 19th Century suggested that we paint a big picture on the Sahara with planted vegetation in the shape of the squares and the triangles the size of U.S. states in that design that proves the Pythagorean Theorem ("the square of the hypotenuse is equal to the square of the other two sides") so that aliens would see it millions of miles away and know that a math literate species lives here.

And then there is that plaque they put on the Voyager craft with the two friendly humans waving, and all of the symbols on it that only recently zipped past the orbit of Pluto and into interstellar space after moving for decades.

But no, I am not aware of anyone on earth actually sending out a sequence of radio beeps in a coded pattern like that though things like that have probably been suggested.

Lets hope they don't find this

If NASA gets their wish advanced aliens will think earth is populated by naked caucasians and they provided directions on how to get to earth. Like an early version of intergalactic Tinder

I meant "pioneer" above, and not "the plaque on Voyager". Carl Sagan was involved with both the probe and the plaque.

The two figures on Pioneer are purposely racially ambiguous (and they look more like Samoans than like White folks to me).

There are a number of things wrong with the figures on the plaque
For one thing the male is the one greeting aliens which indicates the male of out species is dominant while the long haired female is subservient

Carl Sagan himself regretted the figures looked unambiguously Caucasian and not panracial...most people at the time thought it was not representative of wider humanity

Finally the decision to make the figures naked was perhaps the silliest decision given nobody on the planet actually walks around naked

IMHO they shoulda depicted them reproducing.

That would be really interesting!

not the least of which woulda been the reaction of the amuuurican fundies when they caught wind of such.

You're assuming that they would interpret such body language the way most people on Earth do. They're aliens, remember?



There were some silly people who wanted to put shorts on the male, and a bikini on the female (because you Americans are just so damn prudish), but apparently Carl Sagan vehemently opposed this because (and rightfully so) he wanted a representation of what we all look like naturally. If the figures had been wearing clothes, the aliens, if they ever found the spaceship, would just have ended up becoming extremely confused, and would have thought that it was an integral part of our biology.

The truth of the matter is that if there really are intelligent species out there, they will do their best to remain hidden from us. They will avoid contact with the primitive, beastly, violent and destined-for-extinction human race, knowing full well that as soon as it became practical the neo-cons in Washington would ask N.A.S.A. to search for fossil fuels on their planet, and then they would make up a story about how they have weapons of mass destruction and that we need to launch a pre-emptive invasion.

The smart thing for them to do is lay low, and just wait for humanity to destroy itself (which should be within the next 20 years or so). They just need to be patient.

Unless they're sick, evil bastards just like us.

Lordy, just imagine if aliens are plagued with such retroactive ideas, too!

I find myself agreeing with your points Lintar, they make sense

If intelligent life exists (which is likely) and they are even 100 years more advanced (potentially up to millions of years) they probably are aware of earth like planets and probably mapped out our solar system a long time ago.

And yes, I don't think they want to send us signals like SETI because they probably look at us a little like a "conservation park" left to our own devices. Perhaps humans appear on their version of cable TV like "animal planet"
